Liverpool boss Brendan Rodgers says his players have to keep a close eye on Arsenal star Alexis Sanchez on Monday night.
The Chilean is not yet back to full fitness but is still expected to be in the starting line-up when the Gunners host the Reds at the Emirates.
"Arsenal, like many teams, are still trying to find rhythm and flow but while doing that you want to win," Rodgers told reporters on Saturday.
"West Ham got a good result there but with [Alexis] Sanchez back he is a real catalyst for them and they played well at Crystal Palace. It is a challenge we are looking forward to.
"If you assess games against Arsenal we have always had dominance of the ball, especially at home. If you assess the last 10 games Arsenal have lost at home, it was about dangerous possession for the teams who won.
"They only averaged four shots on target with 43% possession. That tells you you don't need to dominate the ball but you can dominate the space.
"That is important in the away games.
"Tactically we'll arrive in a good mind about how we can win it. There are certain games you look at the approach to get you the result and that is something we have been working on this week."
